To all whom it may concern:

Be it known that WILLIAM E. WINE, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, has invented certain new and useful Improvements in Car-Door Ven tilators, of which the following is a specification.

My invention relates to new and useful improvements in ventilators, and more especially'to ventilators which are to be used in the side doors of freight cars, although, as will be understood and appreciated as the description proceeds, these ventilators might be used in other parts of the car or in other structures, in fact, wherever ventilators of this general type are desired.

One of the objects of the present invention is to provide a ventilator which is very economical in construction, it comprising but two plates which are identically formed, one plate, however, being inverted and reversed before being secured to its co-operating plate.

Another object of the invention is to provide a ventilator which consists of two plates, each of said plates having louvers pressed therein, which plates before being assembled, are turned face to face the one being inverted, to thereby form the complete ventilator which will allow a free circulation of air in the car but will prevent ang water from entering the same.

till another object of the invention is to provide a ventilator consisting of two identically formed plates, which may be pressed out in great numbers and only necessitating, of course, the one set of dies.

In the present embodiment I have shown a plurality of ventilators as they will apcar when inserted in a car door of novel esign, although the ventilators may be used in the ends of the car, or in. the sides of the car, or in fact, wherever desired.

With these and other objects in view, the invention consists in certain new and novel constructions and combination of parts as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing the preferred embodiment of the invention,

Fig. 1 is a view in elevation of a freight car door, showing four ventilators installed, three of them, however, being brokenaway for the sake of clearness.

Fig. 2 is an enlarged vertical sectional view taken on line 22 of Fig. 1.

Fig. 3 is an enlarged elevational view of the plate of the ventilator, and v Fig. 4 is a fragmentary vertical sectional View similar to Fig. 2, but on a still further enlarged scale.

Referring now more particularly to the drawings, there is shown in Fig. 1 a freight car door 1, the frame consisting of the usual upper rail 2 and the lower rail 3, as well as the stiles 4 and 5, the lock rail 6 and the mullion 7, to thereby form the four openings for the insertions of the ventilators rather than panels. There is also shown the further uprights 8 in the center of the openings to which the ventilator plates are secured as will be later described.

Around the edges of the four openings and on both sides of the door a slight portion of the wood is cut out so that the ventilator plates, as to be hereinafter described, will set in a slight distance rather than lie flush with the surface of the door frame.

Along the lower rail 3 there are shown a plurality of short grooves 9, and similar grooves 10 formed along the lock rail 6, which grooves extend up into the slightly cut out portions located at the bottom of the plates in the several openings.

Referring now specifically to the manner in which the ventilators themselves are formed, and referring first to Fig. 3, there will be seen a plate 11 which may be of any desirable thickness in which are pressed inwardly, as seen from Fig. 3, the plurality of louvers 12, which in the present instance, are arranged in two vertical series leaving a center strip 13, an upper rail 14, a bottom rail 15, and the two side strips 16 and 17 about the plate. The louvers 12 are preferably pressed in the plate by suitable dies, a slit being out along the upper edges of each as at 18, and the metal then ressed downwardly or inwardly if viewe from out its surface and merging at its ends with the side portions 19.

As will be noticed from the several views,

there is a slight strip of metal 21 left between each of the louvers 12.

Around the edges of the plate 11 is provided a series of openings or holes 22 as well as down the center strip 13 for the reception of the bolts 23.

vThe ventilator is assembled by placing the plate 11 in its opening, as shown in ig. 1, the size of the plate being such that it fits snugly therein and after which another plate 11 is then inverted and reversed in position and placed in the opening but from the rear of the door. This turning end to end of the plate and reversing of the plate causes the two outer faces 20 of the louvers 12 in each plate to lie adjacent and overlap each other, as clearly shown in Figs; 2 and 4.

After these two plates 11 are in position, the bolts 23 are passed through the openings 22 in the two plates and also through holes formed along the edges in the Wooden frame and in the uprights 8 and locked with bolts so that the two plates will be held tightly against the frame work and in a fixed position with relation to each other.

The corners of the door may be reinforced by the gussets or end plates 25 as clearly shown in Fig. 1.

It will be practically impossible for any water to pass through the ventilator as the lowermost portion of each of the rear registering louvers is much higher than the top portion of each of the front registering louvers. However, should any small amount of water, enter the outer plate, it may drip out through the grooves 10 in the lock rail 6 and the bottom rail of the door.

Furthermore by providing the sides of the louvers integral with the front faces thereof, it will be impossible for the water to blow in from either side of the louvers. From the foregoing it will be seen that I have provided a ventilator which is formed of two identical plates, each having inwardly pressed portions or louvers formed thereon, one of the plates being inverted and the two plates then placed face to face and then securely bolted to the wooden frame and fixedly held with relation to each other. It will also be understood that louvers of other configuration or other arrangement might be equally well used, the gist of the invention being that when the two plates are placed face to face and inverted the louvers will lie adjacent and form a passageway for the circulation of air but prevent' any water from being blown therethrough. 1

Many slight changes might be made withoutin any way departing from the spirit and scope of the invention.

Having thus described my invention, what I claim as new and desire to secure by Let the front face of each louver extending at an angle to the body of the plate and hava ing integral sides merging with the front portion of the plate, a second plate similarly formed and connected with said first mentioned plate and spaced apart there from, the second plate being arranged face to face with the first mentioned plate and in an inverted position, so that the angular faces of the louvers contact and overlap to thereby provide restricted openings through said plate.

3. A ventilator comprising a plate having louvers formed therein and in spaced relation with each other, said louvers havin flat front angular portions and integra merging side portions, a second plate of identical construction and placed face to face with said first mentioned plate and in inverted relation with said first mentioned plate, so that the front flat portions of the louvers overlap to form angular unidirectional passageways in said ventilator and means for holding the plates in fixed vrelationship with each other.

4:. A ventilator comprising two plates each having depressions formed therein and said depressions being open along their one edge, the two plates arranged face to face and one plate inverted 'with respect to the other so that the depressed portions of the two plates will contact throughout the greater part of their width, and each of the registering openings of the depressions in the front plate being lower than each of the registering openings of the depressions in the rear plate when the plates are assembled, and means for holding the plates in fixed relation with each other. v

5. In combination with a freight car door frame, ventilators fitting within said frame, each of said ventilators comprising two plates having identically formed louvers therein, the plates being placed face to face and the outer of said plates being placed in an inverted position with respect to the other so that the louvers extend inwardly and form a passageway unbroken in direction, a portion of the louvers of one plate overlapping a portion of the louvers of the other plate, and means for holding the plates 10 to the door frame.

In testimony whereof I aflix my signature.
